. this invention has been parts operatively connected to the 1 ol' the wearer and attached to the wearerls i It will be seen from Fig. 3 that tension on the cord ll causes the hand to swing toward the palm side, whereas tension on the cord 12 will swing the hand in the reverse direction, it permitted to do so by a release of the tension on the cord 11. If the fingers of the hand are normally urged to a position for engaging the thumb, so as to grasp an interposed article, as hereinbcfore described, then tension on the cord 12, if resisted by tension on the cord 11, will cause the hand to open, as illustrated in Fig. 3 Now, referring to Fig. 1 it will be seen that, by reason of the fact that the cord 11 extends from the hip to the shoulder on the same side of the body, an ele\ ation of the wearers shoulder, so as to elongate the distance between 5 said shoulder and hip, will cause a pull to be exerted on the cord 11. A similar movement of the other shoulder will, for like reai l son, exert a pull on the cord 12. In this manner the wearer of an artificial right arm may, by raising the left shoulder, cause the hand to swing on the wrist joint, and by lifting the right shoulder, cause the finger n-iechanism to open the hand. When the right shoulder is lowered, the hand will close and grip any article which may be interposed between its thumb and fingers. l These movements, together with the normal 3 movements of the wearers upper arm and the stump of the lower arm, enable him to bring the artificial hand to any desired position, and open and close the hand at will 1 in any position.'
